Did you try tightening those 8mm bolts on the oil pressure regulator cover yet? If you still have your rack out, I would give it a try. Mine were loose and the cover was wet with oil.

Thanks Jamall....I am retightening every bolt that I have access to....some are tight and some need to be tighten just a little bit more....still need to do the oil pan and anything else underneath.....

Thanks Doug....I'm going to stay with the original for now....as the 94 won't have a ton of mileage accumulated moving forward....appreciate the info...

Did more repainting today...and parts came out really good....for anyone interested....I really like the Rusoleum 2X paint and primer series a whole lot....especially the Aluminum paint....which is sail to be a Metallic....but really spreads well and IMO doesn't have a ton of Metallic in it....giving you the more smoother look of Aluminum...again JMO....I have used Eastwood's paints and they are also good...but the 2X is really working extremely well for me and available at HD for a reasonable price....some pics....[emoji16]
Pic #1...was debating on painting or leaving natural....glad I painted...
Pic #2...brackets and tube also look good...
Pic #3...spare crossover pipe I had purchased....small dent...but no hole in one of the pipe neck's like my original...(which I might JB weld)... before paint...
Pic #4...after paint...
Pic #5...the 2X that really like...
Pic #6...also like this series as well...used this on the sway bars and brackets...and also the crossover pipe in Pic #4...20210330_135212.jpg20210330_211836.jpg20210330_141241.jpg20210330_212542.jpg20210330_151708.jpg20210330_151840.jpg

It is not correct for LT5 fitment. The factory pumps have threaded holes on all three mounting points of the pump housing to bracket. The CC offered pump has just one at the 12 O?clock spot. The holes at the 9 and 3 spots are not threaded, meaning you would need new bolts with nuts to secure the pump to the bracket. Problem with that is there is zero room behind the pump for anything, just the pump housing. Also the back of the factory pump is notched at the 9 and 3 O?clock spots so that the main pump housing can fit into a recess in the head. The CC pump does not have this provision, so the pump will not mount in the bracket, which must also align with the AC compressor for a bolt to go through.

Not sure who sourced those and is marketing them as a direct replacement, but they are not. I am awaiting a refund after returning mine because I tried to use one of those offered by CC for ZR-1s.

... thought it sounded too good to be true.

Since painting the coolant pipes 5 years ago and since they had some slight chips and marks on them....it was time to sand them down and repaint once again....also repeating myself.....I like this paint....
Pic #1...sanded....
Pic #2...both pipes with two full coats and drying on the vise... they came out really good.....20210331_122208.jpg20210331_131226.jpg

A multitask vise got-to-like it.
What kind of paint did you use?

Thanks Roadster I found it on post 652.

Glad you found it mpiecyk....

Need some opinions....as you can see in Pic #1....the replacement high pressure hose is not exactly the same configuration as the factory hose....as there is a slight bend near the connection to the pump...which the replacement hose does not have.....and the factory hose obviously gives more clearance between the line and the pulley...
Pic #2...shows the distance between the pulley and the tube...and that is with me bending the tube slightly....
Pic #3...is the measurement I get between the pulley and the tube... pulley spins freely....but I'm feeling a little uncomfortable with the clearance and don't want to destroy the tube by bending more... now the AC line looks to be about the same configuration as the factory line with which looks like the correct bends... in Pic #4....

Thoughts.....

These parts are now fully dried and very satisfied with the results....looks like I will also redo the plenum...but will be somewhat of a challenge....since I am not going to remove the cables...thinking of a large "spray box" to keep the paint dust contained and spray the plenum before installing....20210401_123048.jpg

Alot going on this afternoon....removed the brake MC and the LF caliper.... taking the rest of the MC apart tomorrow....
Probably common knowledge...but you will need a 14mm (front line) and a 12mm (rear line) flared wrench to remove the attaching brake lines from the MC and a 13mm socket or wrench for removal from the brake booster....
Pic #1..looking at the bottom of the resovoir and you can see the crud buildup that has been going on for who knows how long....
Pic #2..although the fluid is somewhat clear in this jar...inside tells a different story...
Pic #3...if you look inside the resovoir at the top...you can see where I moved some of the crud buildup....
Pic #4...also with the resovoir removed...the crud is more prevalent....when you enlarge the pic...
Pic #5..."O" rings from the top of the cylinder....enlarge the pic to see how the crud buildup attached to the rubber....
Pic #6...after a good cleaning and washing...one "O" ring looks new... the other still have a spot or two where it appears the crud started eating into the rubber....but is still in great shape IMO......even after a good cleaning and wash...20210405_143036.jpg20210405_143053.jpg20210405_162034.jpg20210405_172755.jpg20210405_173205.jpg20210405_174324.jpg
